Venting

Ask a Plumber

When venting, does your pipe have to exit the roof? Can you come out a gable end, and how far from gable vent do you have to be? Also does your vent pipe have to be 3 inches in diameter or can you use 2 inches all the way through? This is for a large shop/garage.

  1. The venting does not have to terminate through the roof on most high efficient furnaces or hot water tanks. Refer to the manual for pipe size selection as this will be determined by total length of the vent and the number of elbows used. The manual will also show how to terminate the appliance.
